Rev Up Those Sonic Cycles

Labyrinth zone

Hahaha, No.

Also everything else you just suggested is from Sonic 3K, which already has a non-city level: Sky Sanctuary.

a mini-level that with barely anything to it so that the developers won't feel obligated by the original content to replicate the way that Sonic 3 and Sonic & Knuckles' levels had so much content to it, as in gimmicks, pacing, feel and exploration, so that they can slap the same sort of lazy levels in which you do nothing but run forward.

and we'll swallow this bullshit because it's eye-candy and "omg this game is so fast and you see sonic going through all of these crazy loops and railz" fml
